Detailed Description
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
in a first embodiment of the present invention, as shown in fig. 1-5, a consensus method for attaching a blockchain of related chain computing power is provided, the method comprising:
step S1, receiving at least one group of service data in a first time period of the block chain network, and solving through Hash operation to obtain a first service Hash value matched with the service data;
it is worth mentioning that the generation of the first service hash value may be to perform hash operation on one or more groups of service data as a whole; the first service hash value may also be generated by performing hash operation on each service data in a merkel tree form, and then generating two superior hash values in pairs until a merkel tree top hash value is solved, where the merkel tree top hash value is the first service hash value;
in this embodiment, the length of the first time period of the local blockchain network is not limited, and optionally, the first time period is a block generation period of the local blockchain network; optionally, the first time period is independent of a block generation period of the blockchain network.
Step S2, according to the first service hash value, generating and announcing a first transaction matched with the first service hash value on a first relevant block chain outside the block chain network; marking the first service hash value as an unconfirmed hash value and writing the unconfirmed hash value into a first block of the block chain network;
in the embodiment, a plurality of or all service data in a first time period are packed as a whole into a hash value and issued in a transaction form on a first correlation chain; it should be noted that the first time period is unrelated to the block generation period of the first correlation chain, in this embodiment, only the first transaction needs to be issued to the first correlation chain, and the confirmation time of the transaction is related to the setting of the first correlation chain itself, so that the block chain network only needs to wait for the confirmation of the transaction. For example, in a bitcoin network, a bitcoin transaction is initiated, which can be accounted and confirmed by absenteeism in the bitcoin network after waiting a certain amount of time, and written into the blockchain.
Step S3, detecting whether the first transaction on the first relevant blockchain is confirmed at regular time according to the first service hash value;
optionally, a plurality of nodes of the local blockchain network may perform data monitoring on the first relevant chain, so as to obtain information on whether the first transaction is confirmed; optionally, a plurality of nodes of the local blockchain network are connected to the local blockchain network and also connected to the first related chain network;
the first initiator of the first transaction receives the confirmation information of the first transaction relatively timely. Optionally, receiving first confirmation information that a first initiator of the first transaction is confirmed about the first transaction; the first initiator is connected with a local block network, and the first initiator is connected with a first related chain network;
step S4, in response to the first transaction is confirmed, collecting transaction record information of the first transaction, recording the transaction record information on a second block of the local blockchain network, marking the first service hash value as a consensus hash value, and writing the consensus hash value into the second block; the transaction record information includes a block number of the first transaction on the first correlation chain.
The present embodiment provides a block chain consensus technique, wherein when the hash value of the related service data is confirmed on the first related chain, the related service data is considered to be not easily tampered and be known. Meanwhile, after the first transaction is confirmed, the related transaction information, such as the first service hash value of the service data, may be confirmed in which block of the block chain.
In practical application, the number of the service data packed at one time is set according to the number of the service data of the block chain, transaction handling fee and the throughput capacity of the first related chain network; it is worth mentioning that when a higher single service data packing amount is set, the commission fee for issuing the first transaction on the first related block chain can be reduced, and the load of the first related block chain is reduced, and on the other hand, when the single service data packing amount is less, the transaction confirmation speed can be effectively improved.
In this embodiment, the receiving at least one group of service data in a first time period of the local blockchain network, and solving through a hash operation to obtain a first service hash value matching the service data, further includes:
acquiring each service unit of the block chain network received in a first time period; the at least one group of service data is composed of the service units;
solving the unit hash value of each service unit;
and generating a top hash value of the Mercker tree according to each unit hash value and the Mercker tree algorithm, and taking the top hash value of the Mercker tree as the first service hash value.
It is worth mentioning that when the hash value of a certain layer of the merkel tree is odd, a single hash value that cannot be paired two by two can solve the hash on itself to obtain the hash value of the previous layer.
In this embodiment, optionally, the method further includes: and recording the service unit or the service data in the first block.
Alternatively, the service unit or the service data may be written into the block of the local blockchain network.
In this embodiment, the periodically detecting whether the first transaction on the first relevant blockchain is confirmed according to the first service hash value further includes:
communicating with backbone nodes of at least three different networks on the first associative chain, periodically detecting whether the first transaction of the backbone nodes of at least three different networks is confirmed; the number of the main chain links is odd;
in all of the main chain nodes, if the first transaction is confirmed by more than half of the main chain nodes, the first transaction is considered to be confirmed.
By setting different main chain nodes, connection with a single main chain node is avoided, the first transaction confirmation of the block chain network is determined by the main chain node, and when the node is broken, the data of the block chain is not credible. Meanwhile, by the adoption of the plurality of main chain nodes, data of different main chain nodes can be compared in time, transaction results confirmed by more nodes can be selected, the phenomenon that main chain branches cannot be found early due to a single main chain node is avoided, and the influence of first related chain branches on the block chain network is reduced.
In a practical application scenario, the main chain node of the first related chain may be set at different mines. Because the same mine field generally excavates the ore collectively, and the time delay of dredging the network is few, and the data in the mine field is relatively unanimous, so can select the different main chain nodes of different mine fields in order to obtain the transaction record information of first transaction.
In this embodiment, optionally, the method further includes:
after the first transaction is confirmed, collecting the transaction record information of the first transaction;
and in response to the change of the transaction record information of the first transaction, changing the transaction record information on a second block of the local blockchain network into the changed transaction record information of the first transaction.
Inevitably, the divergence of the first related link may cause the network data of the local block link to need backtracking change, and at this time, the related transaction record information of the first transaction is changed. If the block chain network employs chain-connected blocks, hash operations need to be performed on all blocks after the changed block, and the data of each block needs to be determined again.
In this embodiment, optionally, the method further includes:
after the first transaction is confirmed, collecting the transaction record information of the first transaction;
responding to the change of the transaction record information of the first transaction, and sending a link data change request to a link internal node of the block link network; after receiving the chain data change request, the chain internal node requests second transaction record information of the first transaction from the main chain node of the first related chain corresponding to the chain internal node, and changes the transaction record information in response to the fact that the second transaction record information is not matched with the original transaction record information.
It is worth mentioning that in the algorithm-based block chain technique, such as bitcoin blocks, which are generated by miners performing mathematical operations continuously, each block must refer to a block thereon, so that the longest chain is also the most difficult to overturn and tamper, and therefore, the node always considers that the longest chain is the valid block chain, and only miners who dig mines on the longest chain can obtain rewards, which is the most common bitcoin longest chain principle. When two or more nodes account at almost the same time, bifurcation occurs, at this time, two accounting modes are temporarily reserved, and finally, a longer chain block is used as a final accounting book.
In an alternative embodiment, when the first correlation chain has a bifurcation and the node of the local blockchain network performs billing according to whether the first transaction is confirmed, the node follows one of the bifurcations, and if the transaction record information of the first transaction of the local blockchain network changes due to the fact that the first correlation chain selects another bifurcation, the node can modify the transaction record information and correspondingly modify the local blockchain.
It should be noted that, when the blocks of the local block chain are connected in a chain manner, that is, when the hash value of the previous block is stored in the next block, the hash value of the block needs to be solved again in response to the change of the first transaction record information, and the hash value after the change is modified at the same time, it is worth mentioning that, for example, the bitcoin network needs 6 times of confirmation to ensure that the data of the block chain is not tampered, so that only the chain connection between the blocks of the local block chain network within 6 block periods of the first related chain needs to be modified, and the computational requirement is not high.
In this embodiment, optionally, a plurality of nodes of the local blockchain network are connected to the network of the first relevant chain while being connected to the local blockchain network.
Based on the data information, the data information related to the first transaction can be rapidly provided for the local blockchain network.
In a typical blockchain example, the previous blockhash value of the network blockchain is used as an input parameter for solving the next blockhash value, so as to solve the next blockhash value.
In this embodiment, optionally, the previous hash value of the network block chain is used as an input parameter for solving the next hash value, and the method further includes:
and in response to the change of the transaction record information of the first transaction, re-solving the second block hash value of the second block, replacing the second block hash value into a block behind the second block, and correspondingly solving a subsequent block hash value.
In this embodiment, optionally, before the step of marking the first service hash value as the non-consensus hash value and writing the first service hash value into the first block of the blockchain network, the method further includes:
writing the first service hash value into a first hash list; the first hash list is used for storing the service hash value matched with all the service data which are not identified together in the block chain network.
By setting the first hash list, the service hash value which is not commonly known is convenient to be consulted.
In this embodiment, optionally, the method further includes:
and writing the first service hash value matched with all the identified service data into a second hash list.
And the second hash list is arranged, so that the service hash value which is known commonly can be consulted conveniently.
It should be noted that, as shown in fig. 2, after the completion of the block XG L1000 of the first related link network 200, in a time period, the service data initiated by the client of the local block link network 100 is collected, and a service hash value 1 is generated, and a first transaction 1 is generated on the first related link network 200, and further a first transaction 2 and a first transaction 3 are initiated on the first related link network 200, and the first transaction 1 and the second transaction 2 are confirmed on the block XG L1001 of the first related link network 200, and the block is monitored to obtain the transaction record 2, and the transaction record information of the first transaction 1 and the first transaction 2 is recorded on the block BQK L1001-1 of the local block link network 100, that is, the common identification of the service hash value 1 and the service hash value 2 is completed.
As shown in fig. 3, the service data 1-7 are paired pairwise to generate a first-level service hash value, and finally form a first service hash value.
As in fig. 4, there are two common nodes for the present blockchain network 100 and the first correlation chain network 200.
First, the block XG L1001 of the first correlation chain is changed, and the confirmation of the original first transaction 3 occurs from the block XG L1001 to the block XG L1002, and accordingly, the transaction record information 2, the block BQK L1001-1 and the block BQK L1001-2 in the original blockchain network are modified accordingly, and at this time, the nodes of the blockchain network modify the information.
In a second embodiment of the present invention, as shown in fig. 6, there is provided an apparatus for learning knowledge about a blockchain of a correlation link algorithm, the apparatus comprising:
the service hash acquisition module 101 is configured to receive at least one set of service data in a first time period of the local blockchain network, and solve through hash operation to obtain a first service hash value matched with the service data;

a second transaction record changing module 111, configured to send a link data change request to a link internal node of the local block link network in response to that the transaction record information of the first transaction is changed; after receiving the chain data change request, the chain internal node requests second transaction record information of the first transaction from the main chain node of the first related chain corresponding to the chain internal node, and changes the transaction record information in response to the fact that the second transaction record information is not matched with the original transaction record information.
It is worth mentioning that in the algorithm-based block chain technique, such as bitcoin blocks, which are generated by miners performing mathematical operations continuously, each block must refer to a block thereon, so that the longest chain is also the most difficult to overturn and tamper, and therefore, the node always considers that the longest chain is the valid block chain, and only miners who dig mines on the longest chain can obtain rewards, which is the most common bitcoin longest chain principle. When two or more nodes account at almost the same time, bifurcation occurs, at this time, two accounting modes are temporarily reserved, and finally, a longer chain block is used as a final accounting book.
In an alternative embodiment, when the first correlation chain has a bifurcation and the node of the local blockchain network performs billing according to whether the first transaction is confirmed, the node follows one of the bifurcations, and if the transaction record information of the first transaction of the local blockchain network changes due to the fact that the first correlation chain selects another bifurcation, the node can modify the transaction record information and correspondingly modify the local blockchain.
It should be noted that, when the blocks of the local block chain are connected in a chain manner, that is, when the hash value of the previous block is stored in the next block, the hash value of the block needs to be solved again in response to the change of the first transaction record information, and the hash value after the change is modified at the same time, it is worth mentioning that, for example, the bitcoin network needs 6 times of confirmation to ensure that the data of the block chain is not tampered, so that only the chain connection between the blocks of the local block chain network within 6 block periods of the first related chain needs to be modified, and the computational requirement is not high.
In this embodiment, optionally, a plurality of nodes of the local blockchain network are connected to the network of the first relevant chain while being connected to the local blockchain network.
Based on the data information, the data information related to the first transaction can be rapidly provided for the local blockchain network.
In a typical blockchain example, the previous blockhash value of the network blockchain is used as an input parameter for solving the next blockhash value, so as to solve the next blockhash value.
In this embodiment, optionally, the apparatus further includes: the block data modification module 106 is configured to re-solve the second block hash value of the second block in response to the change of the transaction record information of the first transaction, replace the second block hash value into a block after the second block, and correspondingly solve a subsequent block hash value.
In this embodiment, optionally, the apparatus further includes:
a first hash list management module 107, configured to write the first service hash value into a first hash list; the first hash list is used for storing the service hash value matched with all the service data which are not identified together in the block chain network.
By setting the first hash list, the service hash value which is not commonly known is convenient to be consulted.
In this embodiment, optionally, the apparatus further includes:
and the second hash list management module 108 is configured to write the first service hash value matching all the identified service data into a second hash list.
And the second hash list is arranged, so that the service hash value which is known commonly can be consulted conveniently.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
